Mechanical tillage is gaining prominence as a food production technique in the savnna region of Nigeria. A cechanical cultivation method was compared with a zero cultivation practice and the traditional cultivation method involving a hoe. Soil mositure content was significantly higher (P=0.05) under zero tillage than undeer mechanical tillage or traditional hoe tillage systems. The stability of aggregates less than 2-mm diameter and the mean equilibruium infiltration rates were significantly lower under mechanical tillage. No significant differences were found between zero tillage and manual tillage. Soil bulk densities in the 0-5 cm depth, differences in bulk densities between tillage treatments were not significant.Nutrient ion distribution in the soil varied with the tillage system. Total P an dK levels were higher in the surface than in the sub-surface soils under zero tillage, but not under the other tillgae systems. Mena maize grain yields (kg ha-1) and cotton lint yields (kg ha -1) under the 3 tillage systems were not significantly different (P = 0.05). However, significant yield differences were observed in some years. Weed population was significantly greater (P = 0.01) under zero tillage than under mechanical tillage. |
